I thought we had a bunch of this stuff? Both via a the existing geotools 
referencing module; and via a warp tool done for last years summer of code.

Cool; can you confirm that this functionality is not already provided as 
shown here:

You can use the Custom CRS to do some of this stuff in an ad hoc manner. 
That said a proper data entry field for these values would be great.

I am not sure I understand it yet :-) Perhaps I am not familiar with GPS 
stuff enough. In general uDig is open for additional contributions; we 
can set you up with svn access and all that. There is a community 
section; and you can have your plugins published for others to access 
from the help menu (we only get more strict with QA checks if you submit 
your code for inclusion in uDig directly).
