The port was made by a couple of students as a term project. They had it 
running on an iPAQ, but with no network connection (they had no time to
spend on selecting a network stack for eCos, getting ppp working, etc.).
Up to now we didn't take this work any further for lack of commercial
demand for it, but that may change soon: as Peter says, acunia and mind.be
are in contact regarding this.

Wonka's internal TCP/IP API is based on Berkeley sockets, so it should be 
no problem to get the Open/FreeBSD stack running: the code we use for 
embedded linux will probably run out-of-the-box. The only thing which 
bothers me about llandre's description is the bit about 4 MB DRAM: 
currently we're not able to strip Wonka down to run in so small a space
(without AWT we need at least 6 MB).
