Custom Hack.

[soniceffect]

In fairness I think your unlikely to get any answers without giving out a little more detail. The question your asking is far too broad. Can you build a 'custom mod/hack'? Some can build small things, other people are fairly good with integrating with other software, others have the ability to write their own forum software if they had the masses of amount of time. Therefore not many are likely to answer as they will be unsure on the level of modification you require.
