Torque engine scalability (from TGE Discussion)

I had the below posted on the TGE Discussion area.
Posting it to TGB as what I really want to know about
is TGB. Sorry if your getting duplicates.

Again, any answer will be greatly appreciated.

-----------------------
I've read good things about the torque engine portability
but not much about how scalable it is, so the questions:

How small can you go with the engine in terms of footprint?
Has the engine been ported, for example, to an ARM9
mobile device, with severe memory limitations, say 4Mbytes
total, with 2Mb for the engine itself. How easy is it to remove
engine features in order to achieve the desired footprint
(assuming code's been feature #if 'ed)?

Any answer will be greatly appreciated.
