I have a customer that desperately needs a Coordinate system solution...Is
Mentor going to have the capabilities of making coordinate systems up on the
fly? I sure hope it does.

Is the current thinking that we pull PROJ.4 entirely out of MapGuide, or
that we continue to support both projection engines through some kind of
configuration?

I see that making Mentor the default projection engine would solve a lot
of headaches for users of Studio and Map 3D, I wonder if there may be
users who will want to continue using PROJ.4 in MapGuide to match the CS
transforms used in their other open source applications.

The press releases have indicated that Mentor will be released under
LGPL.  Is that still the intention?

Frank, (anyone?) do you have any thoughts on how PROJ.4 and Mentor will
be co-existing in the future?

Once Mentor is open sourced you will be able to use the MapGuide API
directly to add/modify/delete coordinate system definitions.
The API is already in open source 2.0 right now it is just not hooked up
to PROJ4.
