in thread Mixing sysread() with <FILEHANDLE>?
Thank you, this is very helpful.
I would indeed prefer not to have to use syswrite. Encoding with pack makes sense, but is there a more space-efficient way to portably transfer the data? Even with uuencoding pack("u*"), there is a 1/3 increase in required bandwidth. (True, SSH compression would mostly negate that if it is enabled, which I can not guarantee).
I need to transmit blobs of raw binary data, up to several gigabytes in a single session hence I do need to optimize for size. For my application, it's the raw bits that are important and need to be preserved. I will never be transmitting any higher-order structure.
Thank you for the advice about encapsulation as well. I have already done that. Now I just need a transmission method that works. :)
