ReadyBoost style app for Cell Phone?

[Magislayer]

Is there some type of app available that will allow me to use the extra memory on my microSD card like a PC uses a flashdrive readyboost program?

I know that cell phones are way different that PC's, but with all the awesome apps and custom ROMS that people like DCD create here, how hard would it be to make an app to extend our phone's memory like this?

The reason readyboost works on PC's is because hard drives can be slow..

Your phone is already using an sd-like memory for internal storage.. so you wouldn't gain anything. (the internal storage on my WM phones is faster then the sd card's reads/writes)

It's been discussed to death already.
