Keep in mind that for 256 MB RAM and higher boards the uncompressed AstLinux image is copied into memory as a tmpfs mount (ie. in RAM). For the special case with less than 256 MB RAM, the AstLinux image is left mounted to the CF card via a loop mount. So for the 128 MB RAM special case, the size of the AstLinux image does not effect the overall system RAM usage. I think the biggest reason we chose to discontinue support of the WRAP and net4801 is the slow CPU speed, which can only route traffic at a fraction of most user's internet download speeds today, let alone also be a PBX. But for special cases like John's they can still be useful with AstLinux.
