[SoC] Re: Request for views on the proposal on pgRouting project.

[Alex Mandel]

This sounds like it might be a good joint project with gvSig,UDig or
OpenJump integration of pgRouting, all are Java implementations of GIS
and UDig is closely tied to the origins of postgis.

I'm not sure who has volunteered to mentor from those projects but it
wouldn't hurt to ask around. This might be a good 2 mentor project.
