iFolder (originally from Novell, now a FOSS project) is a nice cross-platform file synchronization solution - think DropBox or SugarSync. Unlike these it has the advantage that you can run the actual server yourself. Unfortunately, the Linux client, even though it comes as an RPM, only installs on OpenSUSE out of the box. Here's how to get it running on Fedora:

First we need to trick it into accepting a newer library version:

ln -s /usr/lib/libgnome-desktop-2.so.17 /usr/lib/libgnome-desktop-2.so.11

Then we need

eel2-2.26.0-2.fc12.x86_64.rpm

from

http://fr2.rpmfind.net/linux/fedora/releases/12/Everything/x86_64/os/Packages/

which also needs some persuasion:

rpm -i eel2-2.26.0-2.fc12.x86_64.rpm --nodeps

and a symlink:

ln -s /usr/lib64/libgnome-desktop-2.so.17 /usr/lib64/libgnome-desktop-2.so.11

Now it's time to get Novell's OpenSUSE RPMs: download

nautilus-ifolder3-3.8.0.9329.1-4.3.x86_64.rpm
novell-ifolder-client-plugins-3.8.0.9328.1-4.2.x86_64.rpm
ifolder3-3.8.0.10197.1-7.1.x86_64.rpm
simias-1.8.3.10196.1-22.1.x86_64.rpm

from

http://download.opensuse.org/repositories/network:/ifolder:/client_stable/openSUSE_11.3/x86_64/

Install some support packages:

yum install gnome-sharp gtk-sharp2

and then the Simias library:

yum install simias-1.8.3.10196.1-22.1.x86_64.rpm --nogpgcheck

Finally, iFolder itself:

rpm -i  ifolder3-3.8.0.10197.1-7.1.x86_64.rpm --nodeps

Two additional packages provide Nautilus integration and some plugins:

rpm -i nautilus-ifolder3-3.8.0.9329.1-4.3.x86_64.rpm novell-ifolder-client-plugins-3.8.0.9328.1-4.2.x86_64.rpm --nodeps

Final step before we're good to go:

ln -s /usr/lib64/mono/gac/log4net/1.2.10.0__046ed8ba4eae38ad/log4net.dll /usr/lib64/simias/web/bin/

and *drumroll*

ifolder

HTH.
