Well I don't know if Howard is certain but I am sure he's right ;-)

Correction. You can't use it with epppd when you log in, that's why you
don't use it.
You are using fake/simulated BOOTP wheter you like it or not ;-)

Because you gave it that information when you started EPPPD.
Send commands/transfer files (essentially the same thing) are NOT handeld
by BOOTP. BOOTP is only used to get the DNS server(s), your IP, netmask,
gateway (what did I forget?). All commands (like "get" or "put") are then
sent as they always are.

Depends, you can have "simulated" files (links) if the server is running a
UNIX-like OS but not because you use BOOTP in those programs.

That's the point with simulated/fake BOOTP, they think they send a BOOTP
request out on the Ethernet (both EPPPD and LSPPP are faking as packet
drivers for Ethernet, wheras the driver built-in with NetTamer doesn't) but
instead get a response from the packet driver. When I was fooling around
with EPPPD I wondered if this could be scrapped (it isn't really needed, it
just makes things easier) but there were too many who said no. But I
stopped messing with EPPPD not far after anyway.
>Maybe you're thinking about how Windows works???
Actually I would assume that it would work in a similar way. However I do
know that there are diffrences between LAN and modem connections in Windows
(unlike in DOS), this actually makes your speed somewhat slower in Windows
on a LAN - *if* you have long "round-trip times" (high ping to the server).
BTW: Since I had to explain this on another mailinglist a few days ago I'm
close to mentioning RTFM - or Read The Fine Source in this case ;-)
