This is a shame but the idea coming from Windows world. In Win7/Vista there is a feature called ready boost which I suppose do something similar... or maybe not :) the main goal is to break the bottleneck of the slow HDD, but it is maybe a better idea to put some part of the system on a SDHC card which can reside in my bulting SD slot :) I know, this is also removable :)
