Yes I am a very busy guy.  I would love to collaborate with you on
this.  But I don't think that making a new package from scratch would be
a very efficient use of your time.  That is, there are good reasons why
its going to take me a little while to get it to you.  There are a lot
of things to do.  I agree that an organism based package is what is
called for here and that is what I was planning to work on. 

As for your immediate needs, all you should need for GO stats or GSEA is
an environment which you could make for yourself from the appropriate
information.  I can give you those parts in an unformated form if you
want them.   To format them into a proper environment you should only
need to wrap them up in one.

#Lets suppose that we rip off some of the info from the YEAST package to
see how this would work:
res=mget(ls(YEASTGO), YEASTGO)

#Then we could quickly make a couple quick fakey environments:
for (nm in names(res)) MYGO[[nm]] <- res[[nm]]

MYENTREZID <- new.env()
for (nm in ls(MYGO)) MYENTREZID[[nm]] <- paste("fauxId", nm)

#Then we could package them up into a local environments:
MYpkg <- new.env(parent=emptyenv())
MYpkg[["MYGO"]] <- MYGO

#And attach them
attach(MYpkg, 2, "package:MY")

#At this point we should be able to do with these environments whatever
we need to.

I have the relevant information here from NCBI for falciparum to make
both of these environments (for real).  If you send me a personal email,
I can arrange to get it to you...
