I already have a few ideas how to use GLBSE as a pool payment processor and this is also something that would require far less weekly attention + maintenance (don't underestimate this!), maybe you'll hear from me in the future and I'll really claim my ticker symbol (when the share was issued, you couldn't issue subtickers).
Have a look at glibse, the python glbse client library, it's quite easy to use, we now have direct account to account transfers for bitcoin(again with glibse not webclient ATM), you'd certainly be able to use it as a pool payment service.
