So after connecting everything and configuring my computer, everything surprisingly worked for the most part as advertised.  So now that I have my little home network going, why not my Visor?  Xircom was working on a SpringPort Wired Ethernet Springboard module that was due about this time, but it seems that the module has been cancelled.  Xircom's SpringPort page no longer mentions the Wired Ethernet module.  What happened?

Some would ask why an Ethernet module is needed in the first place.  This is a great module for network administrators to test that port that they just opened to make sure that it's on the right subnet.  You now also can telnet into servers, routers, etc and do all your network maintenance without lugging around a separate laptop.

It's also perfect for mobile professionals.  How many offices and tradeshows today have Ethernet connections?  I just walk up to an empty port and plug in.  Bingo!  I can check my email and check my stocks without bothering anyone to borrow their computer for a moment.

I also think that Ethernet would speed up HotSyncs.  A USB HotSync is ~23 KB/s.  Ethernet is 10 Mb/s or 100 Mb/s.  So what I'm envisioning is that you have your PC running with Network HotSync configured.  You then plug in a Ethernet module into your Visor and start a network HotSync that doesn't require a second PC.
