Excellent!

>1. Can brltty be used with the "dialog" program?

Yes. One thing to be aware of is that the best way to ensure that the braille 
device is rendering the desired line is to use the necessary option(s) to 
ensure that the cursor is on that line. This is because brltty can track the 
cursor location, but can't yet track attribute-based highlighting. If possible, 
the cursor should be on the most important character of that line because many 
braille devices are small - in other words, they only render part of the line 
at a time.

>2. Can brltty be used in a framebuffer?

I should know the ansswer to this question, but I don't. No one is reporting 
any problems with this, so maybe it can. Could you please tell me how to know 
if I myself am using a frame buffer console or not? And, of course, if it turns 
out that I'm not, then how do I use one in order to test it?

>3. Does the usage of a true type font for visual display has consequences
>   regarding brltty?

No. Brltty does not do optical character recognitioin. What it does is figure 
out the Unicode character that was used to render a given character on the 
screen.

>4. Can brltty be used with in an UTF8 context? Under what conditions and
>   with which limitations?

Yes. It honours the configured locale of the system. If the locale includes the 
.UTF-8 part then it'll work.
