Sounds like me and Xterms. One for the compiler, one for tf, one for pine,
an editor (xjed), one running rc5des, and a few spares that I forgot I'd
opened. Only three running right now (a small miracle).

Certainly I *do* conceed that two people are fairly unlikely to agree
completely here; since it IS a very interprative issue (is that a word? I
mean; it all comes down to your personal views and outlooks). My client is
actually building up to being 'canned' by the way; it exists as a series
of Java classes (I think some will soon be Java.beans, once I get another
text on them), and will *very* shortly have the ability to automatically
download and update itself (asking for permission first). It'll also
communicate with a servlet to maintain a mudlist (this is further off, but
a similar feature).
Re: security bugs in Java, this is somewhat irrelevant, since you cannot
really code at a more 'basic' level than the language you are using. My
work would be out a bit faster if it were browser-based, but it wouldn't
really do what *I* want it to do (and it'd probably be *less* bulletproof,
since I wouldn't have absolute control over it, or not *as* absolute).

Interesting that you mention this; I intend to allow 'split screens' via a
separate communication protocol (the mud can send information to the
client for display in a separate window, do clickable menus, and so
forth). This would allow this effect to a point; but yes I see what you
mean. Otoh, I can only work in one terminal at once, and I don't really
mind having my screen spammed while I read files (although being able to
read *mail* in a separate window would be very nice).

Well, you could always run multiple instances of a client program for the
same effect. ;)

Hmm. Can you anymore add to a client embedded in a webpage than you can
one which is an application? They'd both just be compiled classes. Unless
you mean adding other things to the webpage, of course. :)

!!! The last application I ever tend to run is a web-browser. And then I
typically use lynx for a few minutes (partly because I don't have enough

This I'll accept as one point (and another reason why playing the
'resources' card is iffy, since it varies from user to user).

It probably averages out; the multimedia aspects of the machine are nearly
non-existant, because I rebuilt it with Linux in mind, and am not a gamer
(meaning Doom, et al).

A lot of this is already available and useable very simply in Java (one
reason which contributed to my selecting it). The only thing missing
currently is sound (not something that really jingles my bells anyway; but
it might be nice in the future).

I didn't even have to do this with my Linux installation. Unpack, make a
few symlinks, party.

I must admit (again) being a bit JScrip ignorant; I've only read snippets
about it, and can't write it (I only do Java currently). I'm looking into
it, though. Another book I'd like to buy *sigh*

Heh. Roguelike games? ;)
