Right now im investigating content deployment options at a client and even after all the infrastructure updates content deployment seems to be buggy still. Its not the fact that its just buggy, its also highly unpredictable.
Sometimes content-types just dissapear in the destination site, or the import/export gives randomly access denied on files while importing.
Its very frustrating to fallback on features & provisioning by code. I wish MS fixed and stabilized their platform first before releasing 2010.
