Alternative clients in regtest mode

[walletfan]

Hello community,
I am working on a student project where I need to simulate the bitcoin network. For some tasks I need regtest mode, testnet is unfortunatly not enough. While bitcoind works fine I have trouble setting up alternative clients like Armory or Electrum. Has anyone experience with that?

The android bitcoin wallet is able to do it pretty easily, but you'll have to change the code yourself.

Do those clients actually support regtest mode? BitcoinJ supports it because I implemented regtest mode for my own use, but I'm not sure if others ever really picked it up.
