We have several commercial clients that have systems based heavily on PHP that we are supporting and have been having trouble finding qualified PHP talent, so remote is definitely an option for us.
That same goes for everyone else here. We're looking for solid PHP talent and trying to avoid having to outsource overseas for it. I had a job posting up but it just came down recently out of frustration from the lack of quality applicants - I can re-post again.
