No, in Germany (from Koblenz to Dortmund). I've used a data card from
a mobile phone company, not the WLAN of an ICE train.

The problem is that the warning messages w.r.t. to Perl-Tk should
*immediately* appear after starting the script, before doing anything
else. IMHO, it's always a good idea to check the prerequisites, then
proceed. I've specifically asked for the GUI on the command line, and
the script should response to that request as soon as possible.

If I start with -gui, I would like that a windows pops up immediately
(similar to, say, Emacs), and all future messages are echoed in that
window. It would be fully sufficient to have something like this:
> ./install-tl -gui
<a window pops up>
Searching uncompressed files...
Searching host in internet...
Downloading TeXLive repository database (this may take some time)...
IMHO such messages are essential; they should be emitted even if I
don't activate a debug switch (at least for -gui).
