Hello, everyone. Sorry I haven't been posting any of my information here. There's currently a mailing list devoted to the subject (started by someone looking to get a group together to bulk-order some of the returning WebPlayers from Merinta) and I've been updating that instead. For those of you here not on that list, it's worth a shot - there's more newbies over there, and the folks on that list are more friendly to them (I noticed earlier someone calling someone else a retard and telling him to wait until someone smarter came up with a FAQ. Not cool). You can find the link off of Slashdot (sorry I don't have the direct link handy at the moment...)
Anyways, I've gotten my WP to work with several OS's so far. Here's details of my setup:
1) 3.5" 4gb HD (with homegrown cable)
2) LinkSys USB Ethernet
I'm currently keeping the hard drive outside of the case (due to size), but once I migrate over to a 2.5", I'll still keep it outside - I'm primarily concerned with heat in the unit, and I don't have the patience to cut holes into the case (besides, it's a nice case, why ruin it?)
I've had the WP working with FreeBSD, Linux (homegrown), Win2K, and QNX. With Win2K, there were the obvious performance issues. Linux worked about as well as could be expected, FreeBSD worked wonderfully, and QNX was great (and proved to be the fastest and most stable).
In the near future, I'm going to be testing with Solaris 8 (x86) and BeOS. For a more permanent installation, though, I'm leaning towards QNX (primarily due to driver stabilty and availabilty, speed, size (it fits on the DOC, with a windowing system), features, and the distributed environment).
One last item: For those of you who have a Linux (or similar) box at home and have a broadband connection, but don't want to get a USB Ethernet controller, take a look in the Slashdot archives for the article explaning how to get a Sega Dreamcast to work with a broadband connection. The steps to take with the WP are almost exactly similar (with the exception of different steps on the WP side) ;).
I'm sorry I don't have more concrete info right now (links and pics), because I'm currently writing this at work. I'll come back later today or early tomorrow with an update (and better links, instructions, etc).
