That code exist for more than a year now ;), it's part of the Obj-C 
interface to R I mentioned a while ago.

There are two approaches - the old one using a single thread (that's 
what my old Cocoa Rgui used - this has several limitations because R 
can block the entire interface) and the more recent one which runs R 
and its loop in a separate thread (very much like JGR). Both are in the 
CVS. The option of using R as a framework instead of plugging Cocoa 
into R has the advantage that the application is a "real" application, 
nut just a wrapper to the R script, which caused quite some problems.

Sounds good :).

AFAIR so far it works in grid only, using gp=gpar(fontfamily="...")). 
JavaGD respects this flag as well as the alpha transparency.

Unfortunately I'll be very busy in the next two weeks, so I won't have 
time to look at it until later this month :(.
