The point about `easy to install TeX' reminds me of a discussion that
went on and off a year or two ago about `what is a decent minuimum
setup'. All of the packaged setups (teTeX, emtex, oztex, miktex, what
have you) take a different interpretation of what a `core' setup
is. They are getting closer, but we are not there yet. I dont propose
to discuss it, but I point out that its one reason why we dont have
`install TeX from this button' links.
Another (related) reason (sigh) is the fact that most packages still
distribute a macro and font tree; so the happy user can't download a
nice portable TDS tree from <here> and a binary for system X from
<here>, because half the setups do not support TDS.
One of the aims of the TeX Live CD is to define and provide a good TDS
tree (packaged at levels 1, 2 and 3 -- albeit rather crudely),
independent of the system. As the CD demonstrates, you can share the
same support tree between Win 32, Amiga, and Unix already.
if all the TeX systems worked in a similar way (I pray to my gods that
Phil will not start saying VMS is The Only True Way To Organize
Files), it would become more plausible to, for instance, distribute a
TDS LaTeX which pulled in `e-TeX' versions of packages if run with
