Is possible to create a symlink for a remote file?
I'm developing an application that reads from /dev/ttyusb0 on remote raspberry. Is possible to create a symlink to the remote device (raspy) on my local development machine?
Thanks!

No.
Symlinks only point to a path – the symlink resolution process essentially just replaces a part of the original name. For example, if you had a path /home/mario/docs/notes.txt and docs was a symlink to ../luigi/documents, the process would give you /home/mario/../luigi/documents/notes.txt.
Therefore you can only create symlinks for something that already has a local path. (For regular files this could be a path provided by a network filesystem such as NFS/SMB/AFS/9p, but devices usually cannot be exported this way.)
If your program only reads & writes data but doesn't use any parameters specific to serial ports (flow control, etc.) then you could create an adhoc tunnel using socat or ser2net on the remote device to link its serial port to a TCP connection, and the opposite on your local machine to link that TCP connection to a "pty".

- https://serverfault.com/questions/360321/forwarding-linux-terminal-from-serial-port-to-tcp-with-socat
But you should implement an alternative mechanism in your application itself – in addition to local devices, it should support e.g. RFC2217 over TCP/IP, which is a common "serial over TCP" protocol.
