Running the latest version of VoxelSniper on a ForgeBukkit server and I cannot get the voxelsniper to go any farther than my click distance.

The only officially supported server is the official Bukkit/CraftBukkit server. I don't know if ForgeBukkit is just a fork of CraftBukkit or if it's a whole custom Bukkit implementation. Either way, there must be something wrong with ForgeBukkit since everything works fine using CraftBukkit.
Furthermore, your bug report is pretty much useless. Have a look into the Readme file (https://github.com/TVPT/VoxelSniper/blob/master/README.md) and read what needs to be included into a proper bug report.

Oh sorry, my bad. If it is in fact a forge thing I'll post a bug report for them as well.

Expected behaviour:
Ability to make long range changes to landscape, buildings etc

Experienced behaviour:
Can only make changes within click range.

Additional info:
Forgebukkit 1.4.7
VoxelSniper 5.168.5
