[somewhat off topic]
Obviously, eg word documents don't grow to large as long as there
aren't, for instance, any pictures embedded to them. If there are,
however, 512k is painfully slow.
Even after the initial opening of the document in Word editing is slow,
not to mention the time it takes for Word to scroll down one page...
The editing problem probably has something to do with the temporary
files word scatters all around, and the scrolling-problem might have
something to do with words crappy loading routines, ie it doesn't load
the whole file straight away.

[back on track]
We run our Lan-Lan-connection with Shiva VPN boxes (encrypting and
compressing all data on the fly), and the ping time is constantly around
30ms (except when the link is full of data), no packet loss (even when the
bandwidth capacity is reached), and our clients are all AMD K7-800 or
PIII-600 running W2K and NT4 (and yes, we have enough RAM :-)).

As a somewhat interesting sidenote, we have noticed that browsing
network shares at the other office from within W2K is much slower than
browsing
them with NT4! Why is that? This is also true for "local" network shares,
but
since we have a lot more bandwidth to play with here, it isn't much of a
problem.
One would think MS would streamline the SMB protocol between releases,
not the other way around ;-)

A 512k link should be plenty, assuming the doc's aren't 50+MB. To
increase speeds, you'd want some fast computers (like PII's if running
Linux/BSD/Solaris, PIII's if doing it under Windows) with low
encryption. That should give you a noticable speed increase.

Out of cursiousity, what's the ping time on that link?
