Yes, the REBOL Palm port lives in a border town next to the
realm of "possibility". REBOL has even been compiled for
Palm before, but the problem is that in order for REBOL to
run (or even to boot) a segmentation paging scheme (virtual
memory) has to be used. Under such a scheme, page faults
would occur constantly. More time would be spent moving
memory than in being an interpreter. As you approach the
problem of a REBOL Palm port, it becomes increasingly
infeasible.
The other approach is to hack the memory protection of Palm
OS. This isn't acceptable, though, because of the potential
for accidentally hurting other apps or data on the pda.
There's still more issues, from Palm's event model and how
REBOL's works, potentially workable, but still an issue.
And how do you write scripts -- in graffiti?? Storing and
load scripts from the database?
Anyhow, there were enough demonstrable problems with it that
we scrapped consideration of the Palm -- to the
disappointment of many.
