Conference room mirroring that works without guest installs

The moment someone realises they have a problem is when a client walks into a meeting room, needs to share their screen, and the mirroring software either can't find the display, requires them to download an app they'll never use again, or lags so badly the presenter talks over frozen frames. This is a recurring humiliation in customer-facing meetings.

The gap persists because the vendors selling mirroring software are primarily selling to IT departments on a per-seat license model. The buyer (IT) is different from the sufferer (the guest presenter). IT buys once, locks the room in, and never sits through a failed client demo. Nobody with purchasing power experiences the pain loudly enough to force a fix. And because the core mirroring protocols (AirPlay, Miracast, Google Cast) are network-sensitive by design, vendors treat lag and drop as a network problem — not their problem.

What currently exists handles the licensed-user case tolerably but completely breaks for the visitor case. One complaint says explicitly: 'each person wanting to connect needs to download the application and have a license, which isn't ideal when a visitor wants to project.' There is no category of product that solves walk-in, zero-install screen sharing to a fixed room display — one that also handles the wifi variability that kills quality mid-session.

This is a business and not a feature because the problem recurs every meeting, in every room, at every company that hosts external guests. The cost is concrete: a failed demo, a rescheduled client call, an IT ticket. The room setup changes rarely but the guests change every day — so the problem is chronic, not one-time.

What to build

Build a small hardware appliance that plugs into a conference room display via HDMI and creates a local, isolated wifi hotspot that guest devices join to mirror without any app install — using browser-based WebRTC screen sharing as the fallback when native protocols fail, with automatic quality degradation management to prevent the 'barely readable' cliff.

Where to start

Target coworking spaces and serviced offices first — they have dozens of meeting rooms, rotate guests constantly, and have strong financial incentive to eliminate IT support tickets from confused visitors who can't connect.

The hard part

Hardware adds cost and a physical sales motion — getting the first 10 rooms deployed requires either a direct relationship with an IT buyer or a channel partner, and a browser-based WebRTC fallback that performs well enough to not embarrass you in a real meeting is genuinely hard to ship without significant latency tuning.

How it makes money

One-time hardware fee per room plus an annual software subscription for management, monitoring, and firmware updates — expansion comes from adding rooms.
