If mining on two copmuters to one wallet works, let us know. And also if it doesn't. FYI, I'm pretty sure you'll need these files from computer A also copied to your BipCoin folder on Computer B:
(wallet name).wallet
(wallet name).address
I have that and I can check one wallet's balance from another computer.
I know it works because I did it successfully on the first day

. But only now it occurred to me that it might not be safe.
Anyway, I like the daemon method better. I have batch files so everything is just a one-click job anyway
Here, for anyone to use:
daemon
@ECHO off
SET ADDRESS=YOUR_ADDRESS_HERE
SET /p THREADS=Miner threads :
IF %THREADS% EQU 0 (bipcoind.exe) ELSE (bipcoind.exe --start-mining %ADDRESS% --mining-threads %THREADS%)
simplewallet
simplewallet.exe --wallet-file WALLET_FILE_NAME --password PASSWORD
