Subject: Re: [fuse-devel] OSS Proxy Jack slave

Hello,

Nope, it's not required for osspd but it's a rather strong limitation on the interface which would be pretty difficult to work around later.  Page protection tricks would be very cumbersome and unscalable.  Hmmm, it does remove the necessity for allocating kernel pages, right?  Still, it seems like a big limitation.  Are you sure this is a good idea?

Thanks.
