Going along the path .....

Do you need the true type fonts MS style.....?
I have installed the microsoft true type fonts using the rpm (Note :- no yum here.).
I now have Arial, Times New Roman and all those fonts in openoffice 3.0 too.

Next is Adobe Reader and Flash plugin....
For the above installs through yum I have had to add the adobe's yum repo (this involves downloading the rpm for the repo installation and then doing a rpm -ivh on the rpm file). My yum.repo.d dir now has repos from fedora, rpmfusion and adobe.
yum install flash-plugin
(I read it somewhere, that if we donot have sound for the flash videos then we need :-
yum install libflashsupport)
For the adobe reader I used the following..
yum install AdobeReader_enu


GNOME MP3 Preview...
I love this feature.... preview MP3 files in GNOME when you hover the mouse over them.
yum install mpg321
Configure this option in GNOME, open the File Manager (Nautilus) and go to Edit > Preferences > Preview and do the necessary selection.

Remotely launching your applications on to a XServer across the network.....
Starting XClient applications across the network - You can create a XServer out of your linux distro by just listening for TCP connections and usign a xhost +ipAddress command.
Fedora 9 had a problem with the X server it couldnot be started to listen for tcp connections. Do a ps -ef |grep X and you should see the --nolistenTCP flag in front of the X server. That means any other user can't export his X client applcns to your xserver.
Fedora 10 has overcome that problem. Open the /etc/gdm/gdm.schemas and look for the DisallowTCP section and change the value from true to false. Now restart your XServer with a Ctrl + Alt + Backspace and you should be able to start X without the nolisten TCP option.
