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. -jeff
