Certainly the washer bottle solution is not the ideal one in terms of capacity and shared with the windscreen washer, but if you are after a Meth solution that can be installed/removed very quickly, the washer bottle is the best for that hands down. If you are happy for a more in depth install, a seperate tank is the way to go.
I am pretty sure all the meth solutions could be configured either way. I know the Vishnu option can be.

Adrian, what are your thoughts on the tank and tank being separated for the under hood version? The only prototype I've seen has the pump just above the charge pipe.
