LMCE would benefit from having these great applications integrated from the get go. However, it's not difficult to install them on your own after the fact.
Oh, this little exercise also made me realize that I have to move to XBMC for my media management. LMCE just isn't cutting it for me in this area and that's all I use LMCE for. Thus, I'm turning my LMCE server into a KVM host and will virtualize LMCE. A network bootable XBMC image will run from another KVM on the same host. I'll still use LMCE for whole home audio (still to be setup) and other home automation coolness.
