It should be able to be loaded to just about any page you want so you can fit it around your things, itll nick a couple of unused system vars to track a few things but again these will be documented.

I'm a bit confused about all this - how will this all work from a technical point of view? I don't know what hardware ethernet controllers tend to have... presumably the ethernet controller can self assemble packets, then the z80 will run a TCP/IP stack and the various HTTP protocol-related tasks? Are you planning to claim well- defined pages and publish well-defined entry points/etc, or just offer the TCP/IP and HTTP code for linking directly into programs that want to use it? Quite possibly I'm asking the wrong questions. If so, please don't hesitate to say so! Re: the SD/MMC card and reading it on full-size computers, I think there isn't a solution yet for Trinity-format cards (?), presumably for us people using an OS with a UNIX layer, this is just a case of someone writing something to find the correct block device and read it back in the expected formats, and could even be added to something like FUSE (the filesystems in userspace one, not the Spectrum emulator)? How hard would it be to add to Sim Coupé?
