could lwnbd automatically wrap content plugin to ioman in a transport plugin and offer local connection on a file I/O API ? It'd reduce driver depend on ioman wrapping (ie: udptty) .
BDM is another tentative to make a common interface for PS2 block device, acting same like lwnbd. It's a shame to miss the opportunity to have a functional and universal interface regardless of the type of device, but that's the social situation of this project at this moment. Bringing out the possibilities of being able to share a common software interface from an input device like a gamepad to a storage device is not easy without having to show all the possibilities that this kind of thing offers.

add SMAP use of lwip too (at least with BUILDING_SMAP_PS2IP) localhost ? iperf ? https://gitlab.com/ps2max/ps2sdk/-/commit/c4b71b54b83964dacb95ca66782f33100d98507e
in-game OPL uses another stack forked from SMS :
- SMSTCPIP is old stripped lwip port (2003) with option to use less memory (#define INGAME_DRIVER).
- SMSUTILS is asm memcpy
- SMSMAP is outdated SMAP comparing to PS2SDK but get more delta.
