Command Line Waveform Viewer

Are there any waveform viewers that work on the command-line only? Something that would work if I ssh'd into a remote machine.

This will be for debugging Verilog code, so all I really need is a way to jump around in time and view the values of the various wires and registers.

I am doing the simulations through ModelSim's vsim, so the output is a wlf file.

Thank you!

As a side note, this is part of my desire to find a way to do Verilog work from an iPad+Wireless keyboard. Sounds silly, I know, but it's more of an interesting adventure than something productive.
