The first should be fairly easy, I'm not sure about the second. I would be willing to have a stab at implementing this if it where likely to be accepted by the devs.

Damn, should have read the whole thread first, apologies.  I think any 
reasonable dev is unlikely to accept that proposition. The app needs to 
be written and tested, I think it would work, however I think one can 
only expect the dev's to consider something concrete.  Similarly using 
the frontend network interface its possible (I think) to write something 
that can be independent of the code, so long as it complies with the 
protocols it could remain independent of the code.  I think that 
something tested and working for a number of people is likely to get a 
favourable hearing from the dev's, but I can't expect them to commit to 
anything before they see it.

An obvious issue to me is how many frontends will be coordinated slaves 
and how will they be controlled in the various combinations?
