The whole point is to use the existing core protocol; the Render extension is efficient enough for normal usage as it sends the glyphs only once. Connections requiring compression for this operation should probably be run through ssh in any case; a general stream compressor does remarkably well on glyphs while not adding any complexity to the protocol at all. I've sent glyphs either as strike-format images (many glyphs in one bitmap), or as long lists of rectangles. The latter works better for very large glyphs as the wire size grows linearly with glyph size instead of quadratically. This also has the advantage of semantic simplicity -- the core FillRectangles request matches the desired rendering operation precisely, while the bitmap format requires rasterop fumbling or messing around with stipples. I'm also planning on doing anti-aliasing for TrueColor visuals; that will require a round trip per string to fetch the destination drawable contents, render the string and retransmit the updated image. I believe I can do this asynchronously with existing Xlib mechanisms to eliminate the latency problem from conventional implementations; I've done similar things with GetProperty when designing a remote file system on top of the X protocol.
