Yes, the module itself would be tricky to get hold of, they're not a part that is sold into distribution. You order n hundred from the manufacturer, wait up to 3 months, and then they deliver them to you. To give an idea, they are something like $25 each when you buy 1000 of them.

You then need the PCB and fairly off-the-shelf components; it's all surface mount though. The controller is a TSSOP PIC which is a pain to program (you need a socket adaptor) but everything else on the board, with the possible exception of the antenna connector, should be buyable from places like Farnell. ISTR there are about 50 components on the board (module, ~4 ICs, ~6 transistors and lots of passives).

The case needs custom punching though, which could well be an issue unless you get it done in volume.

All in all, it'd be a lot simpler if we (or maybe someone else) collected orders and got the original factory to do another production run.

I suspect if someone approached us who has experience with dealing with turnkey manufacturers and was willing to collect orders, finance the run, and then sell the modules for a reasonable profit (I suspect that we're looking at making something like 30-40% margin if sold at the same prices as before in 1000-off volume) then we could do something about licensing them rights to make the design. It's probably going to be easier to do this than get SONICblue interested in making more parts for an EOL product.
