1 Comments on various aspects of KRfb:
3 - KRfb has been designed for three use cases:
4 * a user who needs help from an administrator or friend. The adminstrator can
5 connect to the user and change settings and so on while both are talking
6 on the telephone or using VoIP.
7 * a user who wants to show something to a friend, so he lets his friend
8 connect to his computer
9 * (advanced use case) somebody with several computers, that are running
10 GUIs, wants to control them.
11 - cases 1&2 are probably more mainstream and more important for novice users,
12 so KRfb is pre-configured for them. Case 3 is for advanced users and
13 therefore a little bit more difficult to configure.
14 - design goal of KRfb is to make it as easy to use as possible. I tried to
15 limit functionality whereever possible.
16 - the new-connection-dialog is extra large and has the pixmap on the left
17 side to capture the attention of the user before allowing a connection.
18 - the RFBController class is a mess. The interactions between the threaded,
19 callback-using libvncserver and the event-driven, single thread qt GUI are
20 quite complicated and I can only hope that it works.
21 - most limitations and problems of KRfb are caused either by limitations of
22 Rfb (for example no proper authentication of users, no encryption) or
23 by lack of a framework in Linux in general (no way to connect through a
24 NAT device). In the next months I am going to concentrate on improving the
