Con No Linux version
ShareMouse is available for Mac OSX and Windows only. No Linux at this time.
Con Paid features
Many of the advertised features are paid, so you won't get all the cool stuff for free.
Con Multi-touch gestures don't work for macs
Multi-touch will not work on the other Macs connected to host.
Con Terrible customer support
If it works for you, then great...but don't even TRY to ask for help if something goes wrong.
Con Seriously unreliable
Continuously loses the connection between computers and requires frequent reloading.
Con Has issues with 2-way sync
If you use 2 mice and 2 keyboards simultaneously, there are issues with keyboard focus. For the first PC keyboard to work on the second computer, you need either to use hotkeys to switch focus, or to use the first PC mouse to move the cursor to the second computer. If the cursor is moved by the second PC mouse, the first PC keyboard focus will not switch, causing a confusion, when one keyboard works on both computers, but the other keyboard works on one computer only.
Con Could not get the 2 Macs to connect
It connected for two seconds then disappeared from one of the machines.
Con Windows only
You're running a linux box or a Mac? Then Multiplicity is not for you, sorry. It runs on a variety of Windows flavours, but it doesn't support anything but Windows.
Con License fees
Unless using the 30-day trial, this software costs a minimum of 9.99 USD, which only gives access to a limited number of the multitude of features.
