Also, VST3 support is not in Ableton Live (9), so any VST3-only plugs will not work there.  Version 10 is coming out soon, but it is not known if VST3 will be available.  Not sure if all other DAW's have VST3 support.  They most likely do, I would imagine.  It's new (and useless) technology.

Basically, from my experience, anything that is VST should port over and can be used within other DAW's.  There are exceptions to the rule, however.  For example, some VST's are coded to work only in Sonar.  If I recall correctly, the Nomad Factory FX and the TruePiano instrument both DO NOT work in other DAW's.  Furthermore, the tried-and-true Sonitus plugins DO NOT work as well since they are DirectX and not VST's (Steinberg).

Adaptive Limiter is a vst-plugin but it's only available to be used in Sonar version 23.5.0 or higher.

Reaper still supports DX.

Older plugs like si drum, strings and piano work. Pro channel modules purchaswd separately like CA2A work. Older dx ones work with the few DAWs that still support DX like reaper. Rapture works. Not sure about rapture session. Z3ta also works

Hey that's cool!  +1 for Reaper!
 
I suppose there are a lot more incompatibilities out there that I know.  Trying to solve it in writing is fruitless.  To the OP, just experiment by creating a folder of shortcuts to all of the plugin folders that Cakewalk references and see what works in demos of other DAW's.  Probably out of all the DAW's available, Ableton may be the most limiting, as of the current version 9.7.x.  Still no VST3 support, no DX support, but everything else is rock (and I mean ROCK) solid.

There is a DX to VST wrapper that works.  I have it installed but I'm not sure I've used it for a long time.
