Modified client with lower fee (or don't force it)

[mrx]

If I modify the client about min tx fees(not free), say I changed it to 0.00001024, or even remove it, and send a tx with the modified client, will the tx be accepted by the network? Is there a chance that my tx will never be accepted by the network? if so, will my btc be available again or i'll lose it forever?

Just thinking about this, these question may be noob enough, but I just can't figure them out.

Currently there are rules that require certain transactions (not all, only spammy ones) to carry a minimum fee before it is even relayed through the network. In 0.3.20 and 0.3.21 this minimum is 0.01, in 0.3.22 it is 0.0005, in 0.3.23 it is 0.0001. We're looking for better schemes that do not have such a fixed limit, but for now some spam prevention is necessary. The rules used for creating transactions are an overestimation based on which clients/rules are in use in the network - we don't want transactions that linger forever before being confirmed.

For example my friend and I both mine on my account and I regularly manually pay him (usually about 0.10 every time). So if I really modified the client, it's likely that my tx will be relayed and accepted by the network? I know they'll be low priority txs, but if they can be confirmed in reasonable time I'll accept it.

Probably not. You'd need to find a miner who will accept it and connect directly to him. You can get lower fees by merging the eligius_sendfee branch.
