It rather depends on the data and the consequence of corruption. If
you're willing to put up with undetected errors then going without a
checksum would be OK. Personally I wouldn't though - just because
everything is in software doesn't mean there won't be bugs that cause
corruption.

lwIP can support (for most common operations) both blocking and
non-blocking sockets, so use the same on both. The TCP/IP thread isn't
really relevant.
