Brainstorming - BTC and NMC address with the same private key

[virtualmaster]

I would like to start a brainstorming about Bitcoin and Namecoin address with the same private key.
You can generate with the same private key a BTC and a NMC address.
You have to store less private keys.
But what other applications could use this particular feature ?
If you don't know what I mean look on http://www.namecoinia.org by the merged bitcoin/namecoin wallet.
May be we could find together other uses.

Ufasoft coin uses this same feature.

There were some ideas about using them for Bitmessage too but it seems that this is not easily possible there.

Thanks for the info.

Is there any possibility to make conversion
BTC Address -> NMC Address or
NMC Address -> BTC Address
without knowing the common Private Key ?
If it would be possible then any owner of a bitcoin address could leave a message on the corresponding namecoin address without revealing his private key.

[Sukrim]

As far as I understand it, the address is a hash of the public key. Please correct me if I'm wrong by the way!

This means, as soon as the actual public key is in the wild (typically after a transaction has been made _from_ an address, not just to it) you could calculate any other address with different prefixes, like NMC, testnetBTC and so on.

Namecoin is not used for messages as far as I know by the way, you might confuse this with Bitmessage maybe?

[jackjack]

You can always translate a BTC address into another type of address
Because address = base58( AddressVersion + Hash160)

These are the same address:

Not yet. But this is a possible user case.

Of course it wouldn't have sense using in an identical way like Bitmessage.
But it could have sense to use for information kept forever in the namecoin blockchain, for example to publish a virtual identity associated to a bitcoin address.(email, IRC, messenger, but also other data what the owner of the address wish)
For example:
1.
 - Somebody posts an interesting business idea in a forum and sign it with a namecoin address. He doesn't need to post other contact details.
- You are interested in it and want to contact him. In his namecoin address you can locate additional messages or contact details from him and you can also find out his donation receiving address.
2.
- Somebody is sending to you a higher amount of bitcoins. You know only his bitcoin address.
- If you can transform the bitcoin address to his namecoin address you could find additional informations/messages/contact address and you could thank him.
3.
- A charity organization is posting his donation receiving bitcoin address.
- On the corresponding namecoin address you could find contact address/email and if it is the registration number of the organization.

You can always translate a BTC address into another type of address
Because address = base58( AddressVersion + Hash160)

These are the same address:

Thanks for the answer.
And is there any tool to convert it ?

[jackjack]

I know pywallet does. I can also make a tiny Python script only for this.
I'm not sure any online tool does this.

Then I will try pywallet.
You provided me with very useful informations. Thanks.
A Phyton script would be useful but must useful would be with JavaScript to work on a webpage.
That feature would open new usances based on this property.
As I observed to the same Private Key is belonging  a Bitcoin, a Namecoin, a Terracoin, a Devcoin and a Freicoin address.
Unfortunatelly Litecoin and PPCoin has a different Private Key format.
But may be they are other Alt-Coins also.
This coin address owners which has a Namecoin correspondent(Bitcoin, Terracoin, ...) could store some informations in the Namecoin chain related to this address.
